Continuity mistake: When Ritchie, Eddie, Spudgun and Dave Hedgehog enter the pub with the fake money and order drinks, Ritchie asks for Absinthe but is told that the pub doesn't have any and is given Pernod instead. Later, when the £5000 pub quiz poster is pointed out, Ritchie says he's had half a pint of Absinthe and can't see anything. Where did the Absinthe come from if the pub didn't have any earlier in the episode and they never left?
Continuity mistake: Eddie says that the fairground music reminded him of his dads funeral. But in many of the other episodes Eddie says that he has no idea who his father was.
Bottom's Up - S1-E5
Continuity mistake: When Richie and Eddie are on the roof and Richie starts his rain dance, watch the bottom of his trousers. To start of with he pulls the hem up to around his shins. He then starts and pulls his groin or something and stops and at this point the right hand trouser falls back down his leg. Then straight afterwards in the long shot you can see that it's back up again without him pulling it up.
Revealing mistake: When Eddie ties the string to Richie's leg and slams the door, watch the leg. The jeans actually rip and the fake leg comes out and you can even see the actor's real leg tied underneath. It's really obvious in slow motion.
Visible crew/equipment: When Eddie says "Pork" to Natasha, Richie jumps up and shouts at him. When he says "She is my fiancee", you can see a boom mic reflected in the Elvis Presley photo.
Apocalypse - S1-E4
Revealing mistake: After the piano falls from the ceiling, Ritchie rumbles Eddie's "plan" and kicks him out of the flat. When Eddie is pushed out the front door and down the stairs you can see him falling to begin with, but halfway through he actually stops as if he's kneeling, then ducks out of shot. The sound effects lead us to believe that he's fallen all the way down the stairs and been attacked by a pack of dogs at the bottom.
Continuity mistake: When Richie is telling the other 3 guys to go to the corner, he still has his hands on the wheels of his chair. But when the shot changes and Richie says "if you need the toilet then put your hand up", his arms are crossed around his waist.
Bottom's Out - S2-E6
Continuity mistake: When Richie first gets his head in the fire, the flames become massive. Yet in the next shot, the flames have all died down and all that is left is smoke.
Revealing mistake: When Ade Edmondson clamps the pliers onto Rik Mayall's nose, if you watch carefully you can see the pliers bend a couple of times, showing that they are made of rubber or something similar. (00:13:45)
Revealing mistake: During a few scenes after Richie's finger has been taped back on at an extreme angle, you can see Rick Mayall's real finger bent underneath it. This is most visible after his finger gets slammed in the window: look carefully after the window is opened.
